At Innoflate, we love helping families turn a day out into time well spent together. If you’re looking for things to do in Grimsby with kids, our indoor inflatable park is a great place to start, with bouncing, sliding and sessions to suit different ages. There’s plenty to explore around us too, from local parks and maritime history to nearby Cleethorpes. Here are 15 ideas, starting with what we know best.
1. Bounce, slide and play at Innoflate Grimsby
Make our inflatable park in Grimsby the active part of your family day out. Children can tackle obstacle courses, explore climbing features and enjoy the slides, with indoor fun that doesn’t depend on the weather. Whether you’re filling a school-holiday afternoon or getting together with friends, it’s a chance to put screens aside and get moving.
Our timetable includes Open Bounce, toddler-friendly Innotots and Relaxed ASN sessions, alongside Nerf Wars and Disco Nights. Choose the session that suits your family and check its age and supervision requirements before booking. Our café offers somewhere to pause for refreshments, and birthday party packages are available if you’re planning a celebration.
Check our session times and prices to plan your visit and book your preferred slot. Then, if you’d like to make a full day of it, add one of the nearby ideas below.
